CAR PART.

SPECIFICATION forming part of Letters Patent No. 790,037, dated May 16,1905.

Application filed February 26, 1904. Serial No. 195,344.

T a/ZZ whom t muy concern:

Be it known that I, ETHAN I. DoDDs, of Avalon, Allegheny county,Pennsylvania, have invented anew and useful Improvement in Car Parts, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings, forming part of thisspecification, in which- Figure 1 shows in plan View a blank indicatinghow it is cut to constitute a car part Figs. 2-

in accordance with my invention, and 3 are car-sills made from the blankof Fig. 1. Figs. 4`, 5, and 6 are cross-sections illustrating likeconstructions of sill. Fig. 7

on Sheet 2 is a perspective view ofv a vcar-` frame whose sill,flying-transoms, and bodybolsters are made in accordance with my presentinvention; and Fig. 8 isa perspective view showing a modification.

The purpose of my invention isto construct curved cut edges are withoutintegral flanges.

I then divide the section 2l at the middle by a transverse cut c c,making two parts 2l 2. The section 2 will constitute a sill, bolster, ortransom according to its size, and for this purpose I provide it alongthe cut edge with a reinforcing angle or a flanged piece 3. (Shown inFig. 2.) I may also make a sill, bolster, or transom of the parts 2' 2,and for this purpose I place them end to end with the larger` endsabutting, as in Fig. 3, connect them by tie-plates 4, and apply alongtheir cut edge a reinforcingflange or anglepiece 3.

In Fig. 6 I show a center sill constructed as above described, theoriginal integral flange K 5 of the blank being on the upper margin andthe lower curved cut edge being reinforced by the attached angle-pieces3 3.

In Fig. 4 I show a center sill made in accordance with my invention b vplacing two of the members.- 2 2 side by side in parallel position andreinforcing them along the lower cut edges by the angles 3 3 andconnecting them at the top and bottom with plates 6 6 or otherwise. froma channel-section. The integral rolled iianges 5 5 of the originalblanks are 'at the top of the sill.

'In Fig. 5 I show a construction similar to Fig. 4, in which the members2 2 are made of I-beam sections.

In Fig. 7 I show a car-frame whose end sills 7 7, side sills 8,body-bolsters 9, and flyingtransoms 10 are made as above described, andtogether they constitute a cheap frame of great rigidity and strength.

Instead of making the body-bolsters and transoms continuous, as shown inFig. 7', they maybe built up, as shown in Fig. 8, in which case members2 2 are abutted against opposite sides of the center sill.

Within the scope of my invention as defined in the claims a skilledmechanic will be able to modify the construction i`n various ways, sinceWhat I claim is- 1. A car part having along one edge an integral rolledHange and having its other edge a curved cut edge, having an attachedangle or flanged piece along the cut edge; substantially as described.

2. A blank for a car part composed of a flanged beam slit with a curved'cut substantially longitudinal of its web and a transverse cut throughits web and flange; substantially as described.

In testimony whereof I have hereunto set my hand February 25, 1904.
